Coom ransomware is the cryptovirus that gets released on the system to encrypt common files and make them useless. Developers designed the threat to then release a ransom note READ_IT.txt that directly states what the victim should do next – pay at least 0.015BTC., the ransom can differ from victim to victim, depending on the target and the value of stored and affected files. The particular file is not displaying much information, only stating that the person needs to pay to get those files unlocked and how to obtain Bitcoins for the payment. There is no contact information that could help to communicate with virus developers, so victims have not many options.
